This document provides detailed metadata (data dictionary) for the new simplified NZ Roads and comprehensive NZ Roads datasets published on the LINZ Data Service. These datasets contain a new structure for the road data that we currently hold as part of our address information, kept for electoral purposes.

Please read: This layer provides linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

A linear geometry in this layer will consist of the individual road section geometries (as opposed to the NZ Roads (Addressing) layer where these have been aggregated). This layer has been simplified from LINZ’s NZ Roads database, a centralised database for the management of national road data. The comprehensive set of NZ Roads tables is also available.

These road centrelines do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal.

Some road sections have multiple names; in these cases the non-primary road names are held in additional columns against each road section.

This layer contains the core attributes of a road section to support simple searching with locality and territorial authority or provide a road name context for cadastral data views. This layer is a replacement for the NZ Road Centre Line Subsections (Electoral) layer.

The Electoral road and address datasets will be available until May 2017 to allow users further time to transition.

Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

For this layer (as opposed to the NZ Roads Subsections (Addressing) layer, individual road section geometries have been aggregated to a single road centreline geometry where those subsections share the same name, and are generally contiguous. Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation. This layer has been simplified from LINZ’s NZ Roads dataset, a centralised database for the management of national road data. The comprehensive set of NZ Roads tables is also available.

Please read: This is the table for Road Section Geometry, which is part of the set of NZ Roads tables. The Road Section Geometry table stores the linear geometry for the associated road section, or part of the associated road section.

The NZ Roads dataset includes eight data tables and eleven lookup tables. The dataset has been sourced from LINZ’s NZ Roads database, a database for the management of national roads, including those managed for addressing purposes. This set of normalised tables replaces the Landonline: Road Centre Line layer and the Landonline: Road Name and Landonline: Road Name Association tables currently published on LDS.

These centrelines are required to indicate the presence of an authoritative road name. Named centrelines are not intended to represent the exact location of a road formation. Named centrelines do not indicate the presence of legal access.

This document provides detailed metadata (data dictionary) for the new simplified NZ Street Address and comprehensive AIMS Street Address datasets published on the LINZ Data Service. These datasets are derived from LINZ’s Address Information Management System (AIMS).

The Address Position table contains the point location of an address. An address can have multiple point positions. The Addresspositiontype describes the position E.g. centroid, set back from road. In the first instance the Landonline address position will be used the positioning of this is 'unknown'. Additional Address Position data may be captured over time.

The comprehensive address dataset includes eight data tables and nine lookup tables. The dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes. This set of normalised tables replaces the single Landonline: Street Address layer currently published on LDS.

This layer contains information advised to LINZ by Territorial Authorities (TAs). Under the Local Government Act 1974 (section 319) it is the responsibility of the TAs to advise LINZ (the Surveyor General) of all allocated addresses in their district.

For a simplified version of the data contained within these tables see NZ Street Address.

Local Government Act 1974319B Allocation of property numbers
(1) For electoral, postal, and other purposes the council may allocate a number to any area of land or building or part of a building within its district and may change the number allocated to any such area of land or building.
(2) The council shall comply with any request from a Chief Surveyor to allocate a number to or change the number of any area of land or building or part of a building in its district.
(3) The principal administrative officer shall advise the Chief Surveyor of the land district in which the land or building is situated of the numbers allocated under subsection (1) or subsection (2).

This dataset contains the core components of an address to support simple searching or use of this layer to provide context and is a replacement for the NZ Street Address (Electoral) dataset. This dataset has been sourced from LINZ’s Address Information Management System (AIMS), a centralised database for the management of national addresses, including for electoral purposes.

The existing address and road datasets will be available for 6 months after AIMS go-live to allow users further time to transition.This version will be replacing NZ Street Address (Electoral) dataset.

This source Landonline data exists in order to provide linear geometries against which official road names and street addresses can be recorded. Its purpose is also to enable automated meshblock address reports (for electoral and statistical purposes) so as to identify the presence of a road name in meshblocks where street addresses do not exist.

A road centreline in this layer will typically consist of several road centreline geometries from Landonline that have been associated to the same road name.
In Landonline a road name is commonly assigned to multiple stretches of roading such as between intersections with other roads. A road name is also commonly duplicated across the country e.g. "Queen Street", "High street" etc.

For this layer (as opposed to the Road Subsections Layer. Individual road sections have been aggregated to a single road centreline geometry for each locality. Thus, for example, State Highway 1 has individual sections for differing towns and whenever it crosses a Territorial Authority boundary.

Because some roads have multiple names for part of their lengths, some road centreline geometries will duplicate parts of other roads even though there is in reality only one road formation.

The road centrelines recorded in Landonline do not represent actual road formation, nor do they represent legal access. They must not be considered as topographic, cadastral, or legal.

As a general rule those that are not within a Road Parcels Layer should be treated as being of highly variable accuracy. They do however meet the purposes for which they have been captured, and can provide a valuable resource for other purposes provided that the user(s) understand their origin and consequential limitations.

Warning:
The purpose of the location field is to enable differentiation between roads of the same name in the dataset. It should not be considered official nor part of a valid postal address. It can however be used as an indicative guide to location within a Territorial Authority, or in the case of regional road networks, as an indicative guide to location within New Zealand.
